To all whmn it 72mg concern.-

Be it known that I, EARL E. BARBER, a citizen of the United States, anda resident of Boston, county of Suffolk, and State of Massachusetts,have invented an Improvement in Portable WVindow-Sash Holders or Locks,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention has for its object the production of a simple,convenient, and portable sash-holder adapted to be secured to or removedfrom operative position in a moment, and so constructed that when thedevice is in place the upper sash can be lowered or the lower sashraised only a predetermined distance, thus providing for proper air andventilation while absolutely preventing access to the room from theoutside.

In many hotels the windows of the rooms open onto fire-escapes and thewindows on the lower floors are readily accessible from the ground, sothat intruders may enter unless the window-sashes are closed and lockedBy my invention, which is so small and compact that it can be carried insmall compass by a traveler, the window can be so secured as to afiordthe desired ventilation with perfect safety from intrusion.

The novel features of my invention will be fully described in thesubjoined specification and particularly pointed out in the followingclaims.

Figure l is a perspective view of a portion of the upper and lowersashes of a window with my invention in operative position on the uppersash. Fig. 2 is a vertical section on the line 2 2, Fig. 1, lookingtoward the left and showing the extreme opening movement of the sasheswhen my holder or lock is in use; and Fig. 3 is perspective view of theholder or look detached. I

Referring to Fig. 3, I have shown the sashholder as comprising twosubstantially like members or jaws a 7), made of metal and having flatinner faces and opposite bosses a b on their outer faces near theirinner ends, which are preferably somewhat enlarged, as at a V, to formthe clamping portions. The jaws are extended at their opposite ends, asat a 6 to form a stop, for a purpose to be described, and a threaded rod0 is rigidly secured to one of the extensions, as (f, and adapted topass loosely through a boss 6 on the opposite extension Z2 A milled nutc is mounted on the rod between the extensions. The jaw a is hereinshown as having an upright brace (0 provided with a lateral extension orlug a at its upper end. A strong clamping-screw (Z is loosely passedthrough the boss 5 and screws into a threaded hole a in the boss at, theclamping-screw having a thumb-nut or other suitably-shaped head (Z.

In Figs. 1 and 2 the meeting-rails of the upper and lower sashes areindicated at U and L, respectively, and U indicates an upright divisionmember of the upper sash.

To apply my novel sash-holder, the jaws are separated by unscrewing theclamp-screw (Z until the enlarged portions a 6* will receive betweenthem the division member U, as in Fig. 1, and the sash-holder is'movedup or down thereon until it is at the desired height above themeeting-railsay four or five inches. The nut 0' is then moved with thefingers on the rod 0 to separate the extensions (0 6 a distance equal tothe thickness of the member U of the sash, and then the clamping-screw(Z is screwed up tightly to firmly clamp the holder in place. At suchtime the extensions project inwardly from the member U at substantiallyright angles thereto above the meeting-rail L of the lower sash, as inFig. 1, and the lug or ear (0* rests against the front of the sashmember U above the jaws.

It will be manifest that the lower sash may be raised or the upper sashlowered until the meeting-rail L strikes the extensions (0 6 which thusform a stop, and that thereafter no further opening movement of eithersash can be effected without removing the holder.

The brace a prevents any twisting movement of the holder, for the strainon the extensions tending to turn the jaws on the sash member U is takenup and resisted by the brace, the lug a of which bears against the frontof said member.

My sash-holder can be applied or removed in a moment, it does not mar ordamage the window-sashes, and when not in use can be taken apart, ifdesired, and carried in the pocket. By its use the upper sash can belowered or the lower sash raised only a predetermined distance or bothsashes may be partly open or held wholly closed, as may be desired.WVhen the sash-holder has been applied, no movement of either sash canbe effected beyond the predetermined safe distance.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A portable sash holder or lock comprising separable jaws extended toform a stop, a brace rigidly connected with one of said jaws, and meansto clamp the jaws upon the upper sash of a window with the stopprojecting above the meeting-rail of the lower sash, the brace restingagainst the supporting portion of the upper sash and preventin'displacement of the holder.

2, A portable sash holder or lock comprising separable jaws to embracean uprightdivision member of the upper sash of a window above themeeting-rail, extensions on said jaws to project above and form a stopforthe meeting-rail of the lower sash, a clam ping device to draw thejaws together, and adjustable means to maintain the jaws in parallelismwhen clamped.

3. A portable sash holder or lock comprising separable jaws to embracean upright division member of the upper sash of a window above themeetingrail, extensions on said jaws to project above and form a stopfor the meeting-rail of the lower sash, a clampingscrew extended looselythrough one of the jaws and entering a threaded hole in the other jaw todraw the jaws together an upturned brace on one of the jaws to engagethe supporting member of the sash, and adjustable means carried by thejaw extension to preserve the jaws in parallelism when clamped.

4. A portable sash holder or look comprising two members having meansfor clamping them upon the upper sash above its meetingrail and toproject above the meeting-rail of the lower sash, arigid brace integralwith one of said members to prevent turning of the holder, and means tomaintain the clamping members in parallelism when in operative position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
